Designed and manufactured by SOTABEAMS, this neat bandpass filter is for use with handies (HT) in areas with multiple transmitters. In such areas, many HTs suffer from blocking. This is a ready-made unit – not a kit. Can be used either way round. Just connect between HT and antenna. Our filter is also perfect for use with SDR receivers which may suffer from blocking problems.
